[Problem] Repeated charge and discharge of a nonaqueous electrolyte secondary battery result in gas generation and thus a reduction in the battery capacity. [Solving Means] The problem can be solved by providing a negative electrode for nonaqueous electrolyte secondary batteries including a negative electrode active material having an average operating potential of 0.5 V (vs. Li/Li+) or more and less than 2.0 V (vs. Li/Li+) during desorption and insertion of lithium ions, a conductive aid that is carbon nanotubes having a diameter of 100 nm or less, and a binder that is macromolecules having acidic functional groups.
